技術分野  Technical field
[0001] この発明は横編機の糸長制御に関し、特に編成条件の変更箇所で編地のゥエー ル方向に横筋などが生じることを防止することに関する。  TECHNICAL FIELD [0001] The present invention relates to yarn length control of a flat knitting machine, and more particularly to preventing occurrence of a horizontal streak or the like in the wale direction of a knitted fabric at a location where a knitting condition is changed.
背景技術  Background art
[0002] 横編機ではループのサイズを目標値に近づけて、編地の風合!/、やサイズを一定に すると共に、編糸の使用量を一定にするため、糸長の制御が行われている。  [0002] In a flat knitting machine, the loop size is brought close to the target value, the texture of the knitted fabric is fixed, the size of the knitted fabric is kept constant, and the amount of knitting yarn is controlled so that the yarn length is controlled. It has been broken.
例えば特許文献 1 (特開昭 59— 106548号），特許文献 2 (特許 2952391号）は、 編糸の使用量を測定し、編目のサイズを決定するステッチカムへフィードバックするこ とを提案している。  For example, Patent Literature 1 (Japanese Patent Laid-Open No. 59-106548) and Patent Literature 2 (Patent No. 2952391) propose to measure the amount of knitting yarn used and feed it back to a stitch cam that determines the stitch size. Yes.
特許文献 3 (特許 3085638号）は複数の編糸を使用する際に、代表糸に対し適切 な編成ロックの条件を求めて、他の編糸にも同じ編成ロックの条件を適用することを 提案している。  Patent Document 3 (Patent No. 3085638) proposes to obtain appropriate knitting lock conditions for representative yarns when using multiple knitting yarns, and to apply the same knitting lock conditions to other knitting yarns. is doing.
特許文献 4 (特許 3603031号）は編糸の需要を予測し、必要量を給糸装置側から 積極的に送り出すことを提案している。  Patent Document 4 (Patent No. 3603031) proposes predicting the demand for knitting yarn and actively sending out the required amount from the yarn feeder.
[0003] これらの従来技術で糸長制御に用いられるのは補正テーブルで、補正テーブルの データで編成ロックのステッチカムを制御し編地を編成する。この間、消費糸長を監 視して、所望の糸長になるように補正テーブルを更新する。また編地の種類カ^ブか 天竺かで所望の糸長で編成するための条件が異なるので、補正テーブルはリブ用と 天竺用の 2種類を設ける。  [0003] In these conventional techniques, a correction table is used for yarn length control, and the knitted fabric is knitted by controlling the stitch cam of the knitting lock with the data of the correction table. During this time, the consumption yarn length is monitored and the correction table is updated so that the desired yarn length is obtained. Also, since the conditions for knitting with the desired yarn length differ depending on the type of knitted fabric and the top, there are two types of correction tables, one for ribs and one for tops.
[0004] しかしながら同じ補正データで編成しても、裾のリブと衿のリブとでは、ループ長、即 ちループ当たりの糸長が異なることを発明者は見出した。これは裾と衿とでの編幅の 相違によるものであった。また同じリブでも、 1 X 1のリブと 2 X 2のリブ等では編成組 織 (以下単に、組織）が異なり、同じ補正データでは異なるループ長の編目となること が判明した。さらに袖と身頃などでは編幅が異なるため、同じ補正データでは異なる ループ長となることがあることが判明した。また編成の途中で、スプライサーなどにより 編糸を切断して他の編糸と接続すると、その付近で編成速度を低下させる必要があ る。このような場合にも、同じ補正データでは周囲と異なるループ長の編目となること が判明した。編目サイズが変動する原因は、主として編幅、組織、編成速度の相違で ある。 [0004] However, the inventors have found that even when knitting with the same correction data, the loop length, that is, the yarn length per loop, differs between the hem rib and the rib of the heel. This was due to the difference in knitting width between the hem and the heel. It was also found that even with the same rib, the knitted structure (hereinafter simply referred to as the structure) differs between the 1 X 1 rib and the 2 X 2 rib, and the same correction data results in different loop length stitches. Furthermore, since the knitting width differs between the sleeve and the body, it has been found that the same correction data may result in different loop lengths. Also, during the organization, with a splicer etc. When the knitting yarn is cut and connected to another knitting yarn, it is necessary to reduce the knitting speed in the vicinity. Even in such a case, it was found that the same correction data resulted in a stitch with a loop length different from the surroundings. The cause of variation in stitch size is mainly the difference in knitting width, structure and knitting speed.
[0005] 編地は、糸長を監視し所望のループ長となるように、補正テーブルのデータを更新 しながら編成される。し力、しながら編幅や組織、編成速度が変化する場所で、補正テ 一ブルの更新が追いつかず、編目サイズが乱れ、編地のテクスチャーに横筋が生じ ることが判明した。  [0005] The knitted fabric is knitted while monitoring the yarn length and updating the correction table data so as to obtain a desired loop length. However, it was found that the correction table could not be updated at a place where the knitting width, structure and knitting speed changed, but the stitch size was disturbed and the horizontal streaks were generated in the texture of the knitted fabric.

Accordingly, it is possible to prevent the texture of the knitted fabric from being disturbed due to the disorder of the stitch size, in particular, the occurrence of lateral stripes in the wale direction of the knitted fabric.
[0015] 補正データは例えば補正テーブルとして記憶し、編幅や編成組織、編成速度等に 応じて補正テーブルを少なくとも 3枚、好ましくは少なくとも 4枚、特に好ましくは 6〜8 枚記憶する。補正データを複数枚の補正テーブルで記憶する代わりに、従来通りに 1枚の補正テーブルを記憶し、この他に目標となる編目のループ長を変更するため のパラメータや、糸長を制御するための補正テーブルのデータに乗算するためのパ ラメータを記憶してもよい。この補正パラメータも少なくとも 3種類記憶し、好ましくは 4 種類以上、特に好ましくは 6〜8種類記憶する。  [0015] The correction data is stored as a correction table, for example, and at least three correction tables are stored according to the knitting width, knitting structure, knitting speed, etc., preferably at least four, and particularly preferably 6-8. Instead of storing correction data in multiple correction tables, store a single correction table as before, and control parameters for changing the loop length of the target stitch and controlling the yarn length. Parameters for multiplying the correction table data may be stored. At least three types of correction parameters are stored, preferably four or more types, particularly preferably 6 to 8 types.
[0016] 編地のどの箇所の編成にどの補正データを当てはめるかは、オペレータがマ二ユア ルで指定してもよいが、好ましくは編成データを解析して補正データを自動的に切り 替える。同じ補正データに対して編目のサイズが変動する原因は、編幅や編成組織 並びに編成速度、特に編幅と編成組織にあるので、これらを編成データから解析し て補正データを自動的に切り替えると、オペレータの負担を軽減できる。  [0016] Which correction data is applied to which knitting of the knitted fabric may be designated manually by the operator, but preferably, the correction data is automatically switched by analyzing the knitting data. The cause of the stitch size fluctuation for the same correction data is the knitting width, knitting structure and knitting speed, especially the knitting width and knitting structure. If these are analyzed from the knitting data, the correction data is automatically switched. The burden on the operator can be reduced.
[0017] 編地のゥエール方向（横方向）に沿って、編幅や編成組織、編成速度の異なる複数 のパーツが有る場合、ゥエール方向の途中で補正データを切り替えられるようにする と、編地の品質をさらに向上させることができる。  [0017] If there are multiple parts with different knitting width, knitting structure and knitting speed along the wale direction (lateral direction) of the knitted fabric, the correction data can be switched in the middle of the wale direction. The quality of can be further improved.

発明を実施するための最良の形態  BEST MODE FOR CARRYING OUT THE INVENTION
[0020] 以下にこの発明を実施するための最良の形態を示すが、これに限るものではない。 [0020] The best mode for carrying out the present invention will be described below, but the present invention is not limited to this.
実施例  Example
[0021] 図 1〜図 8に実施例を示す。図において、 2は横編機で、例えば前後一対の針床 4 , 5を備え、前後上下合計 4枚等の針床を備えたものでもよい。 6はキャリッジで前後 に連結され、走行部 8によって針床 4, 5に平行に例えばベルトドライブで往復動する 。 10はコントローラで、キャリッジ 6や走行部 8を制御して横編機 2を駆動し、 12は測 長機で、コーン 13から図示しないキャリアを介して針床 4, 5の針に供給する編糸の 長さを測定する。測長機 12は単に供給した糸長を測定するものでもよぐ編成データ を解析して所要量の編糸を積極的に送り出すものでもよい。  [0021] Fig. 1 to Fig. 8 show examples. In the figure, reference numeral 2 denotes a flat knitting machine, which may be provided with a pair of front and back needle beds 4 and 5, for example, with a total of four front and back needle beds. 6 is connected to the front and rear by a carriage, and reciprocates by a traveling unit 8 in parallel with the needle beds 4 and 5, for example, by a belt drive. 10 is a controller that controls the carriage 6 and the traveling unit 8 to drive the flat knitting machine 2, and 12 is a length measuring machine that feeds the needles 4 and 5 from the cone 13 to the needles 4 and 5 through a carrier (not shown). Measure the length of the thread. The length measuring machine 12 may simply measure the supplied yarn length, or may analyze the knitting data and actively send out the required amount of knitting yarn.
[0022] 14は編成データ入力で、ディスクや LANなどから編成データを入力し、編成デー タはコントローラ 10へ供給される。編成データは解析部 16へも供給され、編地を編 幅や編成組織，編成速度の異同により複数のブロックに分解し、各ブロックの編幅や 編成組織、編成速度に応じて、糸長制御用の補正データを記憶した補正テーブル 1 8を切り替える。補正テーブル 18は少なくとも 3枚設け、好ましくは 4枚以上で、実施 例では 6枚設ける。 6枚の補正テーブル 18のうち、 3枚がリブ組織に対応し、そのうち 2枚が 1 X 1のリブの、編幅が大きいものと編幅が小さいものとに対応し、残る 1枚が 1 X I以外のリブに対応する。 3枚の補正テーブルが天竺組織に対応し、例えば編幅 の大中小に応じた 3枚のテーブルを設ける。解析部 16のデータにより補正テーブル 18が自動的に選択され、選択された補正テーブル中の補正データに従ってコント口 ーラ 10が動作し、キャリッジ 6により針床 4, 5の針を操作して編地を編成する。 [0022] Reference numeral 14 denotes knitting data input. The knitting data is input from a disk or a LAN, and the knitting data is supplied to the controller 10. The knitting data is also supplied to the analysis unit 16, where the knitted fabric is disassembled into multiple blocks according to the difference in knitting width, knitting structure and knitting speed, and the yarn length is controlled according to the knitting width, knitting structure and knitting speed of each block. Switch the correction table that stores the correction data for use. At least three correction tables 18 are provided, preferably four or more, and six in the embodiment. Of the six correction tables 18, three correspond to rib structures, two of which correspond to 1 X 1 ribs with large and small knitting widths, and the remaining one is 1 Compatible with ribs other than XI. Three correction tables correspond to tengu tissue, for example knitting width There will be 3 tables according to the size of large, medium and small. The correction table 18 is automatically selected based on the data of the analysis unit 16, the controller 10 operates according to the correction data in the selected correction table, and the needle 6 of the needle beds 4 and 5 is operated by the carriage 6. Organize the ground.
[0023] 補正データはキャリッジ 6のステッチカムの制御に用いられ、このデータにより針の 引き下げ量が補正され、ステッチのサイズが変更される。従って編目当たりの糸の使 用量 (ループ長）が変更される。編地の編成に用いた糸長は測長機 12で測定され、 編成データ中の編目のループサイズから求めた目標糸長と、コントローラ 10で比較さ れ、この誤差を解消するように補正テーブル 18の補正データが更新される。  [0023] The correction data is used for controlling the stitch cam of the carriage 6, and the needle pull-down amount is corrected by this data, and the stitch size is changed. Therefore, the amount of yarn used per stitch (loop length) is changed. The yarn length used for knitting the knitted fabric is measured by the length measuring machine 12 and compared with the target yarn length obtained from the loop size of the stitch in the knitting data by the controller 10, and a correction table is used to eliminate this error. 18 correction data are updated.
[0024] 図 2にキャリッジの編成ロックを示すと、 2；!〜 24はカムロックで、ここでは前後左右 の合計 4個のカムロックを設けている力 カムロックの個数は 2個あるいは 6個などとし てもよい。各カムロックには左右一対のステッチカム 25, 25が設けられ、それぞれス テツチモータ 26によりカム位置が移動して、針の引き下げ量を制御する。これによつ て編目のサイズと使用糸長が変更される。  [0024] Fig. 2 shows the knitting lock of the carriage. 2;! To 24 are cam locks. Here, there are a total of 4 cam locks in the front, rear, left and right. The number of cam locks is 2 or 6 etc. Also good. Each cam lock is provided with a pair of left and right stitch cams 25, 25, and the cam position is moved by the stitch motor 26 to control the pull-down amount of the needle. This changes the stitch size and yarn length.
[0025] 図 3に補正テーブル 18の構成を 1枚分示すと、テーブル 18のデータはステッチ力 ム 25への補正データである。テーブル 18の各行は、編糸を供給するためのキャリア に対応し、各列はステッチカムに対応する。従ってキャリアとステッチカムとの組み合 わせに対して、補正データが記載されている。  FIG. 3 shows one configuration of the correction table 18. The data in the table 18 is correction data for the stitch force 25. Each row in Table 18 corresponds to a carrier for supplying knitting yarn, and each column corresponds to a stitch cam. Therefore, correction data is described for the combination of carrier and stitch cam.
[0026] 図 4に補正データの構成を示す。編成データ中に編目の目標ループ長が記載され 、もしくは目標ループ長をマニュアルで入力する。次に補正テーブルから読み出した 補正値と、その他の雑補正値とを記憶する。ステッチデータ 30は目標ループ長部 31 と補正値 32並びに雑補正値 33から成り、これらの加算値がステッチモータ 26に与え られる。そして補正値は補正テーブル 18から読み出され、解析部 16により例えば 6 枚の補正テーブルから 1枚を選択する。次に測長機 12により実際に消費された糸長 を測定し、コントローラ 10で目標ループ長と比較して、その誤差を解消するように、使 用中の補正テーブルの補正データを更新すると共に、その糸に関連する他のテープ ルのデータを更新する。  FIG. 4 shows the configuration of correction data. The target loop length of the stitch is described in the knitting data, or the target loop length is input manually. Next, the correction value read from the correction table and other miscellaneous correction values are stored. The stitch data 30 includes a target loop length 31, a correction value 32, and a coarse correction value 33, and these added values are given to the stitch motor 26. The correction value is read from the correction table 18, and the analysis unit 16 selects, for example, one of six correction tables. Next, the yarn length actually consumed by the length measuring machine 12 is measured, and the controller 10 compares it with the target loop length, and updates the correction data in the correction table in use so as to eliminate the error. , Update the data of other tables related to the thread.
[0027] 図 5のガーメント 50を例に、補正テーブルの切り替えを示す。なおこの明細書にお いて、ゥエール方向は図 5でのガーメントの横方向を示し、コース方向はガーメントの 縦方向である。ガーメント 50には天竺パーツ 5；!〜 53が存在し、これらはいずれも編 幅が異なっている。リブパーツ 54〜57のうちで、リブパーツ 56は例えば 2 X 2のリブ 組織で、他のリブパーツ 54, 55, 57とはリブ組織の種類が異なり、リブパーツ 54は身 頃の裾ゴムで、リブパーツ 55は袖の裾ゴムで、リブパーツ 54と編幅が異なって!/、る。 リブパーツ 57は衿のリブ組織で、編幅は袖の裾ゴム 55と類似である。 [0027] Correction table switching is shown by taking the garment 50 of FIG. 5 as an example. In this specification, the wale direction indicates the lateral direction of the garment in FIG. 5, and the course direction indicates the garment direction. It is the vertical direction. Garment 50 has tengu parts 5;!-53, all of which have different knitting widths. Among rib parts 54-57, rib part 56 is a 2 x 2 rib structure, for example, and the rib part 54 is the hem rubber of the body and rib part 55 is different from the other rib parts 54, 55, 57. The sleeve hem has a different knitting width from the rib part 54! The rib part 57 is a rib structure of the heel, and the knitting width is similar to the hem rubber 55 of the sleeve.
[0028] ガーメント 50を編成する場合、リブ組織用の補正テーブルとして、身頃の裾ゴム 54 に 1枚、両袖の裾ゴム 55及び衿の裾ゴム 57に対して 1枚、 2 X 2のリブ組織 56に対し て 1枚の合計 3枚の補正テーブルを用いる。また天竺組織に対して、身頃 51に対し 1 枚、編幅の狭い両袖 52に対し 1枚、編幅が特に広い肩部 53に対して 1枚の合計 3枚 の補正テーブルを用いる。同じ補正テーブルを使用した場合、編成組織が異なると 実際に編成されるステッチサイズが異なってくる。このため 2 X 2のリブ組織 56と身頃 の裾ゴム 54とでは補正テーブルを変更する必要がある。次に編成組織が同じ場合、 編幅が狭いほど編目サイズが大きくなる傾向がある。そこで両袖 52に対しては、編目 サイズが小さくなるように補正データを定めた補正テーブルを用い、身頃 51には中 程度の編目サイズとなるように補正データを定めた補正テーブルを用い、肩部 53に は編目がやや大きくなるように補正データを定めた補正テーブルを用いる。このよう にすると、ガーメント 50の全体に渡って編目のサイズを目標値に近づけ、また消費糸 長を目標値に近づけることができる。そして編地のパーツの境界部分で、編幅や編 成組織などに応じて補正テーブルを切り替えるので、パーツが変わっても編目サイズ が変動することがなぐ所望のテクスチャーの編地が得られ、特にパーツ境界での横 筋の発生を防止できる。  [0028] When knitting garment 50, as a correction table for rib structure, one piece for hem rubber 54 of the body, one piece for hem rubber 55 for both sleeves and heel rubber 57 for collar, 2 X 2 ribs A total of three correction tables are used for organization 56. In addition, a total of three correction tables, one for the body 51, one for both sleeves 52 with a narrow knitting width, and one for the shoulder 53 with a particularly wide knitting width, are used for the tengu tissue. When the same correction table is used, the stitch size actually knitted differs depending on the knitting structure. For this reason, it is necessary to change the correction table between the rib structure 56 of 2 X 2 and the hem rubber 54 of the body. Next, when the knitting structure is the same, the stitch size tends to increase as the knitting width decreases. Therefore, for both sleeves 52, a correction table in which correction data is set so as to reduce the stitch size is used, and for the body 51, a correction table in which correction data is set so that the stitch size is medium is used. The part 53 uses a correction table in which correction data is set so that the stitches are slightly larger. In this way, the stitch size can be brought close to the target value and the consumed yarn length can be made close to the target value over the entire garment 50. The correction table is switched at the boundary of the knitted fabric parts according to the knitting width, knitting structure, etc., so that a knitted fabric with a desired texture can be obtained without changing the stitch size even if the parts change. It is possible to prevent the occurrence of horizontal stripes at the part boundary.
[0029] 図 5では編幅と編成組織の 2種類を問題にした力、これ以外に編成速度が他の部 分よりも大きく異なるパーツに付いても、その境界部で編目サイズが乱れ、横筋が生 じる。このような場合、編成速度が大きく異なる部分について補正テーブルを切り替 えて使用すると、パーツ境界での横筋の発生を防止できる。  [0029] In Fig. 5, even if the part has a force that makes the two types of knitting width and knitting structure a problem, and other parts with different knitting speeds than the other parts, the stitch size is disturbed at the boundary, and the horizontal stripes Is produced. In such a case, if the correction table is switched and used for a portion where the knitting speed is greatly different, the occurrence of horizontal stripes at the part boundary can be prevented.
[0030] 図 6のガーメント 60は、天竺パーツ 61と 1 X 1のリブパーツ 62及び天竺パーツ 63と から成る。天竺パーツ 61と 1 X 1のリブパーツ 62とはゥエール方向に並んでいる。ここ で天竺パーツ 61とリブパーツ 62は組織の種類が異なるので、補正テーブルを切り替 える。また天竺パーツ 61 , 63は同じ天竺であるが編幅が異なるので、補正テーブル を変更する。これらにより各パーツ 6；!〜 63を目標糸長で編成でき、またパーツ 61 , 6 2と、パーツ 63の間の境界での横筋の発生を防止できる。 [0030] The garment 60 in FIG. 6 is composed of a tempura part 61, a 1 X 1 rib part 62, and a celestial part 63. Tengu part 61 and 1 X 1 rib part 62 are lined up in the wale direction. Here, Tengu parts 61 and Rib parts 62 have different tissue types, so the correction table is switched. Yeah. Tendon parts 61 and 63 have the same tengu but different knitting widths, so the correction table is changed. As a result, the parts 6;! To 63 can be knitted with the target yarn length, and the occurrence of transverse stripes at the boundary between the parts 61 and 62 and the part 63 can be prevented.
[0031] 実施例では編地の各箇所で、ステッチサイズを補正するために複数枚の補正テー ブル 18を切り替えた。これに代えて補正テーブルの種類は例えばリブ用と天竺用の 2枚のみとし、編幅、編成組織、編成速度等に応じた補正パラメータを記憶してもよい 。そして例えば補正テーブルのデータに、 1種類の補正パラメータあるいは複数の補 正パラメータを乗算あるいは加減算して用い、あるいはこれらの補正パラメータを目 標ループ長に乗算して用いる。このように編幅や編成組織などに応じて補正パラメ一 タを切り替えると、補正テーブルを切り替える場合と同様に、横筋などの発生のない 高品質のガーメントを得ることができる。なお補正テーブルを 1枚とし、リブ用と天竺用 との補正パラメータを、編幅や編成組織などに応じて合計で少なくとも 3種類、好まし くは 4種類以上、最も好ましくは 6〜8種類記憶しても良い。  In the example, a plurality of correction tables 18 were switched at each location of the knitted fabric to correct the stitch size. Instead of this, only two types of correction tables may be used, for example, for ribs and for sheeting, and correction parameters corresponding to the knitting width, knitting structure, knitting speed, etc. may be stored. For example, the correction table data is used by multiplying or adding / subtracting one type of correction parameter or a plurality of correction parameters, or by multiplying these correction parameters by the target loop length. As described above, when the correction parameters are switched according to the knitting width and the knitting structure, a high-quality garment without occurrence of horizontal stripes can be obtained as in the case of switching the correction table. It should be noted that there is one correction table, and at least three types of correction parameters for ribs and temperaments are stored in total, preferably 4 types or more, and most preferably 6 to 8 types, depending on the knitting width and knitting structure. You may do it.
[0032] 図 7に、実施例の糸長制御プログラム 70を示すと、テーブル選択命令 71は編成デ ータを解析し、編地の各パーツについて編幅，編成組織，編成速度を求め、これらに 応じて補正テーブルを切り替える。編成命令 72は補正テーブルから読み出した補正 データに従って、かつ編成データに従い、編地のパーツを横編機に編成させる。テ 一ブル更新命令 73は、測長機 12で求めた消費糸長と編成データから求めた消費糸 長とを比較し、補正テーブルを更新する。糸長制御プログラム 70は例えば横編機 2 内に記憶させる。  FIG. 7 shows the yarn length control program 70 of the embodiment. The table selection instruction 71 analyzes the knitting data, determines the knitting width, knitting structure, and knitting speed for each part of the knitted fabric. Change the correction table according to. The knitting instruction 72 causes the flat knitting machine to knitting the parts of the knitted fabric according to the correction data read from the correction table and according to the knitting data. The table update instruction 73 compares the consumed yarn length obtained by the length measuring machine 12 with the consumed yarn length obtained from the knitting data, and updates the correction table. The yarn length control program 70 is stored in the flat knitting machine 2, for example.
[0033] 図 8に実施例での糸長制御方法を示す。編成データを解析し、編幅や編成組織、 編成速度等に応じて使用する補正テーブルを、編地の各パーツ毎に決定する。そし て編成データに従い横編機での編成を開始し、編成データでの目標値と実際に消 費した糸長との誤差を解消するように、使用中の補正テーブルのデータを更新すると 共に、その糸に関連する他の補正テーブルのデータも更新する。なお補正テープノレ では糸はキャリアの番号で管理されている。そして補正テーブルを切り替える箇所で 、言い換えると用いる補正テーブルが異なる編地のパーツ間の境界で補正テーブル を切り替え、編成が終了するまで補正テーブルのデータの更新と、補正テーブルの 切り替えとを行う。 FIG. 8 shows a yarn length control method in the embodiment. The knitting data is analyzed, and the correction table to be used according to the knitting width, knitting structure, knitting speed, etc. is determined for each part of the knitted fabric. Then, according to the knitting data, knitting with the flat knitting machine is started, and the correction table data being used is updated so that the error between the target value in the knitting data and the actually consumed yarn length is resolved. Data of other correction tables related to the yarn is also updated. In the correction tape thread, the yarn is managed by the carrier number. Then, at the point where the correction table is switched, in other words, the correction table is switched at the boundary between the parts of the knitted fabric with different correction tables, and the correction table data is updated until knitting is completed. Switch.
[0034] 実施例では、編成の間常時消費糸長を監視し、補正テーブルを更新するものとし た力 サンプル編成とならい編成の 2種類の編成モードを設け、サンプル編成の間に 補正テーブルを更新し、ならレ、編成ではサンプル編成で更新した補正テーブルを切 り替えながら使用して、補正テーブルの更新を省略してもよい。  [0034] In the embodiment, the yarn length is constantly monitored during knitting, and the correction table is updated. Two types of knitting modes, sample knitting and knitting, are provided, and the correction table is updated during sample knitting. However, it is also possible to use the correction table updated in the sample organization while switching, and omit the update of the correction table.
